Mitigation of Circulating Current in Three Phase Quasi-Z-Source Parallel Inverters with PV and Battery Storage

Also Available Domains DC - AC Converters

Project Code :TEPGPS632

Objective

The main objective of this project is to mitigate the circulating currents occurred in the three phase quasi-Z-Source parallel inverters.

Abstract

In this project, an insightful analysis on parallel operation of three-phase quasi-Z-source inverters with photovoltaic (PV) and battery storage on input side. Coordinated operation of PV and battery during charging and discharging mode through self-tuned mechanism is also explained. The analysis also includes PV-battery source dynamics, which establishes an interlink between common-mode voltage (CMV), filter ground, and the load neutral currents. This has been utilized to propose a new controller, which reduces the circulating current in quasi-Z-source parallel inverters fed with PV-battery. The performance of proposed controller is verified through experimental validation under equal and unequal load-sharing conditions. The simulation results can be evaluated by using Matlab/Simulink Software.

Keywords: Battery storage, parallel operation, quasi-Z-source inverter, solar photovoltaics.
